Coherent Stock Plummets 1.62% as $340M Volume Ranks 345th in Market Activity

On October 2, 2025, Coherent (COHR) closed with a 1.62% decline, trading at a volume of $340 million, ranking 345th in market activity. The stock's performance drew attention as investors digested mixed signals from its operational updates and broader sector dynamics.

Recent developments highlighted Coherent's strategic pivot in semiconductor tooling, with analysts noting potential volatility from pending contract negotiations with major clients. A key factor cited in market commentary was the company's decision to delay a critical product launch, which some interpreted as a strategic pause rather than a setback. However, no direct earnings or revenue figures were disclosed in the referenced materials.

Market participants also observed Coherent's position within the laser technology subsector, where competitive pressures remain elevated. While the company has historically benefited from R&D partnerships, recent regulatory scrutiny in its core markets introduced uncertainty. The lack of new financial guidance from management further limited near-term catalysts for the stock.

To run this test rigorously, I need a few clarifications: 1. Trading universe • Which market(s) should we draw the “top-500-by-volume” list from? (e.g., all U.S. listed stocks, only the S&P 500 constituents, specific exchanges, etc.) 2. Price used for entry/exit • Do you want to simulate buying at each day’s close and selling at the next day’s close (standard approach)? • Or buy at next day’s open and sell at that day’s close? 3. Benchmark / performance metrics • Should we compare the strategy against a benchmark index (e.g., SPY) in addition to reporting absolute returns? • Any risk controls (stop-loss, max holding days—beyond the 1-day rule, etc.)? Once I have these details, I’ll generate the rebalancing signals and run the back-test from 2022-01-01 through today.
